IMPROVEMENT. IN SASH-PULLEYS.

TO ALL WHOM IT MAY CONCERN: y

Be it known that I, SIMON DRUM, of the city and county of Allegheny, and State of Pennsylvania, have invented a certain new and useful improvement in Sash-Pulleys; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and lto the letters of reference marked thereon.

The nature of my invention consists in making a new article of manufacture, to wit, a sash-pulley, consistiug'of two side pieces and a pulley or sheave, constructed, arranged, and operating in the manner hereinafter described l lo enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings- Figure 1 represents a front elevation of my improved pulley with -the several parts in juxtaposition.

Figure 2 represents an end view of the same.

Figures 3 and 4 represent an inside view of the sides.

Figure 5 represents a plan for making the mortise in the frame for the pulley and sides.

In the drawings a and b represent the sides, the ends` of' which are furnished with notches marked o, and projecting points marked e; these notches and projections act as dove-tails for holding the two sides in proper relation to each other :v represents openings in the sides for the journals or axis of the pulley or sheave d; z'

represent-s the screw-holes which are used for securing the pulley and sides in the sash-frame. Onehalf of each` of the screw-holes are made in eachof the sides a and b.

'lhe mode of inserting the pulley and its sides in the sash-frame is :1s follows: I take a cent1-mbit, the siz'e of which corresponds to the archof the ends of the sides a and b, when joined together as indicated by the letter c, and witli,tliis centre-bit I bore two4 holes as indicated by the dotted lines mund u, in fig. 5. I then cut out the space between the holes m and n, as indicated by the two lines marked 1,' and j; I then put together the sides a and b and the pulley or sheavc d, in the-manner represented in figs. 1 and 2, and insert it in the recess niortised out n sash-frame, and secure it to its place by means oi' screws placed in the screw-holes marked z',

The advantages oil my improvement in sash-pulleys consist, first, in simplicity of construction, and the ease, facility afforded in casting;` second, saving time and labor in fitting the pnlley'in the sash-frames.

Having thus described the nature, construction, and operation of my improvement, what I claim as offm-'y invention, isv A shell for a sash-pulley, said shell being made in halves and without a face-piece, and so arranged that the openings for the screws are divided by the line of separation between thev halves of said shell, whereby one half of cach opening for the screws are cast in the ends of each half of the shell; the whole being constructed, arranged, and operating substantially as herein described, and for the purpose set forth.

SIMON DRUM.
